Abstract
A liquid crystal display includes a substrate, a gate line on the substrate, a gate insulating layer on the gate line, a data line on the gate insulating layer, a thin film transistor having a gate electrode, a source electrode, and a drain electrode, wherein the gate electrode is connected to the gate line and the source electrode is connected to the data line, a first passivation layer having a first contact hole exposing the drain electrode and covering the data line and the thin film transistor, the first passivation layer having a first resistance, an insulating layer having a second resistance lower than the first resistance and covering the data line and the thin film transistor, a second passivation layer having a second contact hole connected to the first contact hole and on the insulating layer and the first passivation layer, and a pixel electrode on the second passivation layer and contacting the drain electrode through the first and second contact holes.
